Four great reasons to buy your bike from Sigma Sports
Sigma Sports has one objective - to help you find your perfect bike. Our friendly, knowledgeable staff ask you a series of questions to understand what type of rider you are and the type of riding you do. We can then identify the style of bike that best suits your needs.
Riding a bike that fits you perfectly will help keep you injury-free and ensure you enjoy riding further for longer in total comfort. We check your measurements on a jig to ensure your optimal set-up.
When you collect your new bike we'll double-check your position and make any micro-adjustments if required. We'll also discuss the controls on your bike as well as maintenance tips.
We offer a free safety check after six weeks or 200 miles, so you can keep riding in confidence. Visit us now in-store to discuss your new bike.
Trek's highest grade carbon makes the frame incredibly light, stunningly responsive and compliant.
Reliable, precise and efficient, this 11-speed setup never misses a gear change.
The Madone's Kaamtail frame tube shapes make it one of the world's most aerodynamic road frames.
This top tube design uses an adjustable dampener to improve compliance at the rear of the bike.
Trek Madone SLR 6 Disc Road Bike 2021
The frameset of the Trek Madone SLR 6 Disc Road Bike is constructed from their lightest carbon to date. 800 Series OCLV Carbon is stiff yet vertically compliant, and the top tube incorporates IsoSpeed, adding adjustable compliance to further absorb vibrations. An elastomer ensures this damping effect is smooth, controlled and stable. Designed as an aero race bike, the Madone uses Kammtail Virtual Foil tubing to minimise drag so the air flows smoothly over the bike with as little resistance as possible. Further contributing to this design are completely hidden cables, plus an aero stem, handlebar and seatpost.
Shimano's Ultegra groupset takes care of both shifting and braking. The 2x11-speed mid-compact configuration provides a wide range of gears and going between them is smooth, precise and fast. Hydraulic discs bring all-weather stopping power for confidence at speed and on technical circuits. The Madone rolls on 50mm deep Bontrager Aeolus Pro 5 wheels that can be set up tubeless with ease.
- 800 Series OCLV Carbon is the lightest laminate Trek has ever made, and it makes the Madone faster on any terrain, in any conditions
- Adjustable Top Tube IsoSpeed lets you adjust compliance to your preference, and it's damped with an elastomer so it rebounds in a smooth, controlled, stable motion
- H1.5 Fit is the sweet-spot geometry of a low aero riding position that's comfortable on long days in the saddle
- Built for flat-mount disc brakes for extra tyre clearance and all-weather stopping power
- A separate bar and stem with an aero carbon faceplate gives you great adjustability without compromising on aerodynamics
- Shimano Ultegra 11-speed drivetrain and hydraulic disc brakes
- Bontrager Aeolus Pro 5, OCLV Carbon 50mm deep wheels
- The Madone seatpost has an integrated mount for the Bontrager Flare RT tail light
